Stay away from Conan.

"What? Is this true, Hattori?"

Surprised that he received a reply call from Heiji Hattori so quickly, only one night had passed, Conan was both delighted and a little uneasy. After all, this news was extremely important to Conan at this moment.

In response, Heiji Hattori stated with certainty:
"Absolutely no mistake! To confirm this, I came to the hotel where the incident occurred early this morning. After all, speaking of the incident in Kyoto on Tanabata, this fire caused quite a stir in our area at the time!"
“I thought of this as soon as you told me last night, but I wasn’t sure about the details, so I came early this morning to help you verify them.”

"Huh? Is that how it is?"

At this point, hearing Hattori Heiji mention that the fire was something Hattori Heiji could easily have imagined, she couldn't help but be somewhat surprised:
"You've all heard about this? No wonder the killer didn't choose any locations in the Kansai region. If the Kansai police get involved, the connection between the victims might be discovered very quickly..."

As Conan said this, he couldn't help but marvel at the murderer's scheming. There was no doubt that every step the murderer took was meticulously calculated.

In response, Heiji Hattori continued:
"Indeed... However, if that's the case, then the murderer's crimes have probably stopped there. The current seven victims were all survivors who escaped together in the elevator..."

"No! The killer must have had at least one other person as a target!"

However, before Heiji Hattori could finish speaking, Conan immediately added.

"what?"

Somewhat surprisingly, Heiji Hattori wondered what clues Conan possessed that allowed him to say that with such certainty.

Conan then told Hattori Heiji about what Takato had told him the night before—that the murderer chose the location to dump the body based on the corresponding positions of the Big Dipper and Polaris.

Upon hearing this, Hattori Heiji exclaimed in slight surprise:
"I see... As expected of the detective. But then, who is the remaining victim...?"

At this point, Heiji Hattori paused for a moment, then said to Conan, "Wait for me."

Then, standing in front of the hotel in Kyoto where the fire had occurred, Hattori Heiji quickly ran back into the hotel and began asking the hotel staff in detail about the situation of the guests during the fire and whether anything else had happened.

Shortly after, Heiji Hattori replied to Conan:

"It is said that the only person who died in that fire was a girl named Honjo Nanako. She was staying at the hotel with her boyfriend at the time. When the fire broke out, her boyfriend happened to be out and escaped!
"Also, the elevator in this hotel is only big enough for seven adults to ride together!"

"What! I see!" Finally, after hearing this, Conan finally discovered a clear clue that he could investigate:
"The only victim in the fire most likely died because the elevator was overloaded and she couldn't get on. Her boyfriend, who wasn't in the hotel at the time, must have been filled with remorse afterward. In that case... her boyfriend..."

"If he wasn't the murderer, then he should have been the last victim!"

Naturally, Heiji Hattori also thought of what Conan was thinking, and even added the name of Nanako Honjo's boyfriend:
"By the way, according to the hotel register, Nanako's boyfriend's name is Mizutani Kosuke."

"I understand! Thank you, Hattori... I'll take over the investigation from now on!"

With this information provided by Heiji Hattori, Conan knew that the investigation had a clear direction. Therefore, it was no longer convenient for Heiji Hattori to continue participating, since the matter was ultimately under the organization's scrutiny. What if the organization also discovered this and ran into Heiji Hattori…

Now that things have come to this, I don't want to involve others, so I'm just saying this.

As a result, listening to Conan's serious tone, although Heiji Hattori didn't quite understand what had happened to Conan, he could tell that Conan didn't want him to get too involved. Clearly, this matter was not as simple as the case itself.

After a moment of silence, Hattori Heiji said, feigning ease:
"Okay, I'll wait for your good news. You have to tell me how this matter ends..."

"Also, there's a really good monjayaki restaurant that just opened in Osaka. I'll treat you to it next time you come to Osaka!"

In this seemingly casual change of topic, Conan knew in his heart that Hattori Heiji probably had a premonition of something. However, in the end, he had no idea how this matter would end, so for now, Conan could only calmly respond with a "hmm" and then hang up the phone.

And so, with the end of the phone call, Conan, who was inside the Metropolitan Police Department, knew it was time to take action. Coincidentally, Kogoro Mouri wasn't planning on idly staying in the Metropolitan Police Department any longer. After calling Inspector Megure to "complain" and express his opinion that there was no point in staying in the Metropolitan Police Department any longer, although he still had some doubts about the attack that happened last night, Inspector Megure ultimately didn't have time to worry about it, thinking that the other party probably wouldn't launch another attack in broad daylight.

Therefore, Inspector Megure instructed his officers to escort Kogoro Mouri and his group back, and arranged for one or two officers to keep watch near the Mouri Detective Agency as a precaution.

Thus, Kogoro Mouri and the other two successfully left the Metropolitan Police Department. It was at this moment that Conan expressed his desire to visit Professor Agasa's house without encountering any obstacles. After leaving the Metropolitan Police Department, Conan went to Professor Agasa's residence.

Shortly after Conan arrived at Professor Agasa's house, he got into Professor Agasa's car and left with him, heading towards a certain place.

When Professor Agasa's yellow Beetle finally stopped at a certain place, the person who got out of the car was no longer Conan, but Shinichi Kudo, who had returned to his original form.

Seeing Shinichi Kudo return to his original form after taking the antidote in the car, Professor Agasa said to him with some concern:
"Shinichi...aren't you taking too much of a risk?" (End of Chapter)
